Missed Deadline - again!

Well as you can see by the web-cams, we are no where near ready to start the big dig.  So today's' deadline will come and go like many previous.

The deconstruction is now going pretty much to schedule, but we just did not start soon enough due to all the lost time re-engineering the structure to meet the new District policies. May was meant to be tear down month but both April and May were generally spent on re-engineering and drawing and getting the house fully empty.  This is one downside to doing ALL the work myself -  There is no overlap.  In general, I did not start this project prepared.  I had intended to purge and empty the house over the winter, but was generally fully occupied with drawing, redesign, and variance approvals.

I have pretty much given up on a schedule at this point and am just working as hard as I can each day to move forward. The actual deconstruction did not start until May 12 with the removal of the Kitchen followed shortly after by the laundry room.  We then had to prepare for the asbestos remediation. Since the remediation of the asbestos laden drywall completed June 4, I have been able to lift up aprox 650 sq. ft. of beech hardwood flooring (including grinding off nails), removed wood panelling from hallways,  removed all of the wood planking that was installed behind the panelling, and as of yesterday remove all of the non-bearing internal walls.

Front entrance at back left.   White wall used to be bathroom and back right was spare bedroom.  Wall in foreground is the central bearing wall holding up the ceiling joists.

Foreground was dinning room and stack of salvage 2x4.  Room behind brick chimney was laundry utilities and room to right was kitchen.  The few renaming posts are holding up some splicing in the ceiling joists near a roof valley above. Just visible behind chimney is a remaining bearing wall holding up ceiling joists at the south half of the house.
 Over the next week I hope to stack the salvaged wood outside (need to figure out where as really tight on space!), take a garbage and green waste run to the transfer station, pull up the sub-floors (this is plywood screwed to ship-lap, nailed to 2x4 sleepers. When we had the hardwood put in, I installed about 18 pounds of screws in the sub-floor to reduce the creaking that was present.  There is no way I will have the time to remove all of these screws to salvage any of the sub-flooring, so I will just be cutting it into 4ft x 4ft panels and taking to dump unfortunately), and then start taking off the exterior siding.  This should be much easier using the offset for the reciprocating saw I talked about on an earlier posting.

Lets see how well I do meeting this goal.

Thanks for stopping by!

Thermal Bridging - The New Buzz Word

Just a short message tonight.  I finally got around to reading the Winter 2013 Journal of Building Enclosure Design and it was chalk full of articles on the importance of preventing thermal bridging across balcony slabs.

This is a hot topic in most BE circles right now.  Even as little as 5 years ago, most energy models ignored the thermal bridging that results at this interface, but as I wrote a couple of days ago, even though the slab only represent around 3% of the total wall area, if not thermally broken, it can easily diminish the entire walls thermal resistance by 50% or more.

The construction industry and building designers are finally listening to the Building Scientists and realizing that details really do mater!  We need to start building smarter because there are too many Aqua Towers in this world.

Thanks for stopping by and please visit my project journal often as I am posting almost daily now.

RCI Conference

Sorry for the repeat to those that follow both my Blog and Journal, but this info was too good to miss.

Please visit for the lunacy surrounding slab edge thermal bridging, double stud construction, and wrapping buildings in foam.

Thanks For Visiting!

Removing Hardwood Floors - The easy (ier) way!

One of the tasks I was not looking forward to in the demo of our existing house was the task of pulling up the approx 650 sq.ft. of hardwood floor.  I had done some of this in the past and it was a bear.  It is murder on your back and takes for ever.

I put about 2-1/2 hours into it yesterday and did about a foot by 40 ft.  Each row was taking 5-7 minutes and based on this rate the whole living and dinning room (only part of the job) was going to take me 19+ hours.  I started again this morning and after a few rows I was second guessing my decision to save the floors. 

My back is already not the best and I knew that I was not going to last doing this the traditional way.  Almost any example you see of pulling a hardwood floor that has been nailed down uses the following tools.

Typical tools used to take up a hardwood floor.

But I had vowed on this project that I would work smarter and not harder.  I decided to 'waste' half an hour going to the lumber store to see if there was any better options.  Boy am I glad I did.  I ended up buying a 6 lb sledge on a 36" handle and a pick/axe.  Now you may be wondering how these two could work together.  They can't untill you modify them.

The beginnings of a beautiful thing.
 But by cutting off the pick, you are left with a lovely flat spot to whack the 'axe' in under the tongue on the flooring.

Finished tools work very well together
This cut the time per row down to under 2 minutes or a savings of apprx. 70%

This example took just under 4 minutes.  I was able to hone the method down to around 2 minutes per row.
A panel lifter is also useful but in the end, I just used my modified tool to do everything.

 The following is a time lapse of the entire floor removal.  As you can see, the timing spead up considerably with the new tools in hand.

I found that working on the individual pieces from the middle of the piece was the most effective to lifting it out. Often the grove side joint broke, but these will be easily added back with a router. And considering the increase in speed this method afforded, the extra work to put new ends on some of the boards was well worth it.  I will now look to find a labourer to grind off all of the protruding staples (I believe this will be much faster than trying to pull out with pliers).

Thanks For Stopping by.
